crooser Posted March 16, 2004 Share Posted March 16, 2004 The car felt a little stronger with less boost. what plugs/gap are you using? Also does the haltech pull set amounts of timing out when certain knock levels are reached?

B-Man Posted March 16, 2004 Share Posted March 16, 2004 A dyno graph with power, revs, boost and AFRs will reveal your problem. Sumthing is not right - that's for sure.

RNS11Z Posted March 16, 2004 Share Posted March 16, 2004 Hey mate i remember you, i told you to see matty for tuning as you told me you had problems. On matty's dyno i made 340rwhwp yet on the weekend the car made 420rwhp with the same set up except blown manifold gasket and has gone almost 121mph with 4psi less boost of what it was tuned on. I would say it could be your mechanics have either done something to your car or matty isnt tuning it right. As much as you are sick of spending money, your going to have to spend more as there arent many profesional skyline tuners/ builders here in qld if you want pm your contact details and il give you a call harun Link to comment https://www.sau.com.au/forums/topic/36406-300rwkw-club-please-read-i-need-youre-help/page/2/#findComment-727829 Share on other sites More sharing options...
Fitzpatrick Speed Works Posted March 16, 2004 Share Posted March 16, 2004 with a conversion i would also be looking for all air leaks first...everywhere intercololer pipes vacuum lines everything check fuel filter then look at cam timing if adjusted take back to stock then go from there on a dyno. then check plugs and gap. set timing to 20 deg adv at 1200rpm remove exhaust leave just the dump on the dyno check air fuel ration should be around 12- 12.5 to 1 for a good tune run something a little better than a t piece but it doesnt have to be electronic just something a bit better.. check regulator pressure make sure it is aroun 35-40psi at idle the halteck is a map sesor have you totally rewired or bought a plug in harness for it check your map senso is a 3 bar item check you are getting wot some of these are drawing at straws and considering you have made strong power at lower level it leads me to believe there are two problems ignition or fueling.... check coil packs, check regulator and read you ignition maps on higher boost thats what a halteck is good for look at them on the pc... hope this helps!!

help Posted March 16, 2004 Author Share Posted March 16, 2004 Hey guys, thanks for you're responses. I have a heaps of things that need to be addressed by the sounds of things. Last night i was thinking about just ripping the halteck out and starting again. I will get photo's of the stuff you have asked for as I couldn't find an AR no. I am one of those guys that just say's I want to go fast, how much? fingers crossed they do the right thing.

Fitzpatrick Speed Works Posted March 16, 2004 Share Posted March 16, 2004 irs not important as it is still pushing 22psi, which ever way you look at it 22psi is 22psi, only the characteristics of boost delevier and response will be affected by the ar no. on the turbo... eg... 1.06 on my gtr came in a 5800 .86 comes in a 4800 on the same bosst it stil makes the same figures.. the problem is not the haltech they are fantastic computers, they just need someone that knows about haltechs to work on them.... i recomend you call this bloke www.justenginemanagement.com he knows about them more tha anyone he used to make them before starting his own business...

tribex Posted March 17, 2004 Share Posted March 17, 2004 dont know if this helps but we went from 229 rwkw's to 257 just by gettin someone with clues and time to retune microtech on gtr, which also rely on map sensor....aftermarket ecu's can be a real bastard....

RNS11Z Posted March 17, 2004 Share Posted March 17, 2004 It looks more like a 1.0* rear housing. My gt30's rear housing was a .82 and it was way smaller. it seems some were along the line there is a fault with the conversion. Who have you taken it to so far?

PHaT MR30 Posted March 17, 2004 Share Posted March 17, 2004 yeh boost controller can have somethingto do with it, not too likely.. but a mate had a turbosmart dualstage and its was just plain shit removed it and was 10 times better. get a profec b or something similar ive have one and its seriously a good thing and fairly cheap Link to comment https://www.sau.com.au/forums/topic/36406-300rwkw-club-please-read-i-need-youre-help/page/2/#findComment-728713 Share on other sites More sharing options...
RNS11Z Posted March 17, 2004 Share Posted March 17, 2004 Matty, just spoke with Goran. I told him about your situation, he said to give him a call on 3299 4344 and book it in with him. He said it could be a couple of things but i'l let you speak to him. Good luck with it.
